Net-to-Gross Calculator

Use it when reviewing a job offer or negotiating a salary — when you want to first decide on your target monthly take-home and then find out what gross annual salary you need. Because companies quote salaries on a gross basis, reverse-calculating from your target net income helps you set a concrete minimum threshold for salary negotiations.

Net-to-gross (reverse) calculation starts from your desired monthly take-home and works backwards to find the gross annual salary required. It's especially useful during job offer reviews or salary negotiations when you want to know exactly what gross salary you need to achieve a target net income.

Negotiate on gross salary — that's the standard employers use — but anchor your floor with a reverse calculation. Figure out your target take-home first, reverse-calculate the required gross (e.g., 'I need at least ₩49M gross to clear ₩3.5M/month'), then enter negotiations with that concrete number. Also clarify whether non-taxable allowances like meal and commuting subsidies are included, since they can meaningfully raise your effective take-home without changing the stated gross.

This reverse calculator assumes 1 dependent (self only). More dependents reduce income tax withholding under Korea's simplified withholding table, meaning you could achieve the same take-home with a lower gross salary. Use the Salary Calculator to fine-tune the result by adjusting your number of dependents.

Use the required salary figure from the reverse calculation as your negotiation floor. You can also quickly assess the real take-home value of a gross salary the other party proposes. Keep in mind that whether non-taxable allowances (such as meal and commuting subsidies) are included can affect take-home even with the same stated gross salary.

The Net-to-Gross Calculator takes your desired monthly take-home as input and reverse-calculates the gross annual salary needed. The Salary Calculator works in the forward direction — you enter a gross annual salary and it calculates deductions and monthly take-home. Use the Net-to-Gross Calculator when your goal is defined in take-home terms, and use the Salary Calculator when you want to evaluate a specific salary offer.

Yes. Non-taxable allowances such as meal subsidies and vehicle allowances are excluded from taxable income, which can lower the gross salary needed to reach a given take-home target. This reverse calculator assumes zero non-taxable allowances, so if you receive such benefits, your actual required gross salary may be lower than shown. For a more precise result, enter your non-taxable allowance in the Salary Calculator.

Each company structures pay differently — the mix of base salary, bonuses, and non-taxable allowances varies widely. This calculator uses the standard 100% withholding rate, and actual income tax is reconciled at year-end tax settlement. For an accurate comparison, ask the company for a sample payslip, or enter your non-taxable allowance details into the full salary calculator.

This is caused by the progressive income tax structure. As your take-home target rises, you enter higher tax brackets, so the gross salary needed grows faster than the take-home increase itself. For example, adding ₩1 million to your monthly take-home requires a larger gross increase at higher salary levels than at lower ones. Move the slider upward and watch how the marginal tax rate badge on the result card changes.

A good starting point is to add up your fixed expenses — rent, living costs, phone bills — to find your minimum required amount. Enter that figure in the slider to reverse-calculate the gross salary you need, giving you a realistic floor for salary negotiations. Adding your savings target on top gives you a concrete negotiation figure to aim for.
